Half man, half girl. Can drink as much as a college boy, but still has female sex appeal. The most notorious MERL, rumoured to be named 'Noor', attends the University of Colorado at Boulder and can be spotted at the bars on a daily basis on the prowl. Though there is no actual documentation of this MERL, many have claimed to have spotted her on several occasions. Use caution in the presence of a MERL.

"God I love being half man, half girl"
"MERL, you probably shouldn't say that in public anymore"
